To all whom it may concern. v

Be it known that. PETER M. Wnen,-a citizen of the United States, residing at Grand Rapids, Michigan, have invented certain new and useful Improvements in Sheet-' Metal Safes or Gabinets, of which the fol-- lowing is a specification.

This invention relates particularly to. im- "provementsin; sheet metal safes or cabinets,

with sheet'metal walls.

lVhile my improvements are parti available for safes and the like, and I have. illustrated the same .embodied in a safestructure,.the invention may be made use of in doublewalled structures inv various relations' The main objects of this invention are:

First, to provide an improved sheet metal walled structure which is light andsimple and economical to produce and is easily and quickly: assembled- Second, to provide an 1 improved light sheet metal walled structure which is very rigid. Third,v to provide an improved structure of the class described,

in which the passage of heat through the prevented. 2

Further objeots and objects relating to details and economies of construction and v operation will definitely appear from the detailed description .to' follow.- I i I accomplish the objects of my invention by the devices and means describedin the following specification. The inventionisclearly defined and point-- i ed:out in the claims. y

Referring to'the drawing, the structure illustrated comprises anouter wall member having. a rear'wall portion 1, top wall portion 2;, and bottom wall portion 3', formed integrally of sheet metal. These walls are provided with out-turned seam members 4 at their edges? The top and bottom. wall on the rear; top and'bottom wallsl described.

The outer side wall members 7 have. angle port-ions 2-- -and 3am provided; withangle flanges 5', the arms 6 of these angle flanges ,being directedrearw ardly. The outer side walls 7 are provided with'flanges 8 at their top. bottom. and rearedge's, having seam members '9 coacting" withthe seam" members VIII ,and IX.are arranged within the In-practice; the frames'and outer wallsare 1 assembled by engaging the seams of one side wall with the seams of therear top'and bet 1,

them so that the walls may be formed of comparatively light sheetfmetal", and, at'the same time, are very rigid and capable. of

withstanding' heavy loads and racking strains.

The rear frame member 12 'is formed of angle material arranged with its angles facing forwardly and outwardly. Comparatively li ht material is satisfactory and I preferab y form thesame out' from heavy sheet metal. The front frame 13 isalso of angle material" and isarranged in the angle flanges, as stated, and provided with angle extensions 14 which Iproj ectinwardly beyond the inwardly projecting arms of the wall angle flanges, The upright members of the frontframe 13 are provided with arms 15- which. lie against the front walls. See Fig. VI'. I

The rear inner wall 17 is provided with flanges 18 at its edges, arranged to embrace the forwardly-projecting arms of the frame .12. See Figs. II and IV. The inner side walls 27 are provided with shouldered flanges 28 at their rear edges, ,which engage the vertical edges of the rear inner wall-and clamthe same upon the frame 12 as shown in Flg. II. These side walls'are provided with outturned flanges 28 at the top and bottom engaging the top and bottom walls .2 and'3. See Fig. V. The inner side walls are provided with angle-flan cs 29 at their front edges'whichare secure to the angle extensions 14 ofthe-front. frame by means of the screws 25. See Figs. II and VI.- The inner bottom 19 is provided with a shoul deredflange 20 at itsrear end adapted to engage the-lower edge of the rear inner wall and=with an angle flange 21- at its front edge which is secured, to the extension 14 of the bottom piece ofJthe frame member 13. See Fig..IV. Thejtgg with -ashoulder flange 23 at its rear efid adapted to engage the upper edge of the rear inner wall an with an angle flange24 at its front end-secured to the angle extension of I so.

- By this arran the top piece of the frontframe member 13. See Figs. V and VII. The top and bottom inner walls are forced between the-side walls and constitute-'locking-and bracing members. ement'of parts, the walls are simple in, oim and: very easily assembled, and when assembled, the structure is very rigid, although made of light ma-.

. terial. Further, a double walled structure is secured which is of 'very eat advantage in safes and structures of lig t character. The flanges on the inner walls serve as wall spacllg members; 31nd alsoconstituteheat including' elementsfor. the seam joints b'e-- tweemtheiouteri sido-and top and bottom andv ogether and reinforces.

innerwall 22 is provided rearwalls. Owin' ,to the form'of the ioints,

the-same being 0 the interlocking or telescopin seam type, when the walls are expand'e by heat as in a, fire, considerable movement at the joints is possible without opening the same owing to their telescoping relation. This is a very advantageous feature.

In practice, I preferably close the seam by means of blow pipe welding, but this is mainly to secure the appearance of a solid structure, as it is not .an essential for the securing of the parts or making it a ri id structure. The front frame is prefera ly secured to the wall flanges in which it is arranged, byv spot welding. In the structure illustrated, both the inner and outer walls are rovided'with a lining 30 of asbestos.

Tlie doors'31 and 32 are also, chambered or double walled. These doors are formed of sheet metal, the rear edges of the outer walls being turned inwardly or flanged at 33 to form therear edges of the doors and"pro-.

vided with extensions 34 upon which the inner walls 35 are la ped. At its front ed e, the inner wall 0 the door 31 is provi ed with a slipped extension 36, while the front'edge of the outer wall 'is lapped over the same at 37 lapping the outer arm of the .channel' extension of the inner wall.

See Figs. III and X. This .provides a vertical. groove and rib. K

The door 32 is of the same construction at its rear edge asthat described for the door 31'. The front edge of the outer wall of the door is steplped at 38 to coact with the door 31 and is a so conformed to provide a channel 39" for the trou h 41 containing packin material 43. The oor 31- is provided wit provide packing channels 46 and 47. These packing channels are filled with a suitable fire-proof material, such as asbestos or magnesla. To assist in retaining the packing within the channels, I provide strips 48 .whi'chare secured to the wall flanges, as

shown in Figs. VI. and VII. By thus arranging the parts, the channels at the tolps and bottoms of the doors face forward y, while the channels at the edges of the doors face inwardly. The doors are: preferablyprovidedwith vertical ribs 49 'at their rear edges which class into the packing materiaL l lnprac latches of any vsuitable form, preferably tice, this packing is put into the channels in a plastic state and the doors closed against it, when it is allowed to set so as to secure a perfect joint.- p v Casters 51 are secured to the reinforcing bars 52 which are secured to the bottom flanges of the side walls, the caster rivets 52 being arranged therethrough as shown in 3 combination looks, but as these form no part a w of my present. invention,-I do not describe the same herein. By this arrangement of a parts, Isecure a sheet metal walled structure which is strong and-rigid, and, at-the same. time,- simple and economical in structure. effectively. withstands The structure also heat... In practice, the inner, walls areprovided with shelf ledges orother means for supporting the-shelves or the like. I have not illustrated the same'herein as. such supportsform no part of the present invention.

vWhile I have shown my improvements as embodied in a safe, they are also adapted for use in various structures, such as sheet metal boxes andthe'jlike, where it is desirable to'provide alight, rigid 'metal structure, and one which is'simple and economical. A further advantage of'my present construction is that by joining the parts as 'I have shown, a heavymassive appearance is secured which-is desirable in a structure ofthischaracter. v I have illustrated and thereof as rear, top, bottom and side walls. It will" be understood, however,

thatm y inventioii' might be embodied in a structure open at the top. and in such a structure, the walls corresponding to the .top and bottom walls of the structure would become side walls and the rear wall, strictly speaking, a bottom. ,I do not, however,

' wish tobe understood as restricting or' limit 'ing myself by the use of the terms top',

bottom and rear walls but have used such :terms as a matter: of convenience and in the interest of clearness.
